Path loss, fading, and delay spread are the three important radio propagation issues. Explain why those issues are important in a cellular system?
What will be an ideal response?
The wave propagation in multipath channel depends on the actual
environment including factors like antenna height, profile of the buildings, road and the terrain. Therefore we need to describe the behavior of mobile radio channels using a good and relevant statistical mechanism. Thus this is provided by studying the path loss and fading phenomenon to understand about the characteristics of the land and terrain profile. The delay spread is also necessary to understand about the propagation channel, whether the signal is propagating through the frequency selective or the flat fading channels.
